Three types of tea the a,b,c costs Rs. 95/kg,100/kg and70/kg
respectively.How many kgs of each should be blended to produce
100 kg of mixture worth Rs.90/kg, given that the raveled s of
band c are equal...
Answer Posted / jjb
a+b+c = 100
b = c
a.95 + b.100 + c.70 = (a+b+c).90
in this system of 3 linear equations with 3 unknown values, replace c by b , since they are equal:
a = 100 -2.b
a.95 + b.170 = 9000
then:
9500 + b.(170 - 190) = 9000
or:
500 = 20.b
The correct answer is b = c = 25 kg, a = 50 kg.
